How to solve:"Unable to find node on an unmounted component." on entering text

I have integrated Botframework V3 in my React website, incorporate a custom build of the Web Chat component.I have include cdn for style

<link href="https://cdn.botframework.com/botframework-webchat/latest/botchat.css" rel="stylesheet" />

When ever i enter a value in my input tag,i get this error.

WebChat.js

import React from 'react';
import { Chat } from 'botframework-webchat';


export default class extends React.Component { 
  render() {
    return (
        <React.Fragment>
            <Chat 
            directLine={{ secret: ' SECRET_KEY' }} 
            user={{ id: 'user_id', name: 'user_name' }}/>
        </React.Fragment>
    );
  }
}
